At Donor Egg Bank USA™ we use extensive screening to help qualify our diverse selection of egg donors. That includes a genetic test, called expanded carrier screening, to help determine if a donor is a carrier for one or more of at least 100 different genetic conditions. Let’s take a closer look at exactly what that information means and how it can help inform you as you search for your ideally matched egg donor.
Once you complete our free registration, you’ll have access to all our donors’ full profiles and medical histories. Included in each of these histories is information about the specific conditions for which the donor was screened and which conditions she was identified to carry. Of course, not every donor will be identified as a carrier for the conditions that were screened, and some may be a carrier for more than one. The truth is everyone in the general population is a carrier for conditions that are inherited in an autosomal recessive manner. Some of the conditions that individuals are more likely to be carriers for include alpha thalassemia, cystic fibrosis, and sickle cell disease, among others.However, a donor‘s carrier status for a condition does not mean that children conceived using that donor will be affected by this condition. Many of these conditions are recessive, meaning both biological parents have to be carriers for the same condition for there to be an increased risk for a child to be affected. If both biological parents are, in fact, carriers for the same condition, the chance that they will have a child affected with that condition is 25% with each pregnancy.
Here's the bottom line: Even if your donor has been identified as being a carrier for a condition, she could still be “the one.” Because, again, the likelihood of having a child affected with this condition also depends on the sperm provider and his genetics.
So, here are the steps you should take when considering a donor who is a carrier:
Having access to genetic information about your egg donor (and your sperm provider, should they also be tested) offers you an advantage not just for today as you are considering donors, but also tomorrow. Because you now have all this valuable information on record, you can share it with your child should they decide to create a family of their own.
